If I lost my phone it would be a big pain to log into online banking etc, and an even bigger pain if I were away travelling solo. I was thinking of buying an iPad mainly as a back up just incase, but then thought I could just get a new phone and keep the one I have as a back up, with both phones linked to the same accounts. DH says I'm risk averse, and why would I lose my phone? 
Do other people have a back up if travelling alone?
